Korean Paper Decoration Board and Method of Making the Same

The present invention relates to a decorative board and a method of manufacturing the decorative board. More specifically, it relates to a decorative board and a decorative board which can provide a long-term aesthetic design such as a pattern or a picture while maintaining the texture of the paper, And a manufacturing method thereof.

Currently, the interior materials of buildings are widely used as MDF, gypsum board, LPM, HPM, plywood, gypsum board, cement board, magnesium board, silica board and inorganic board, and they are used for finishing panel, flooring, have.

In particular, architectural interior materials mainly made of synthetic resin are widely used as materials for general building materials, furniture, or various household goods, and have been used for flooring, ceiling materials, side wall materials, door frames, and the like.

Such an architectural interior material is a substitute for wood, and it was superior in diversity of design and productivity, but its appearance was poor due to the heterogeneity of materials, and the coefficient of thermal expansion was large, resulting in warping after construction, lack of elasticity, , Most of which are odorous and toxic, the main cause of which is the gradual release of residual formaldehyde and health problems.

Accordingly, in recent years, there has been an increasing demand for eco-friendly interior construction materials, and yellow earth boards have been known.

On the other hand, hanji is a paper made by our country's unique manufacturing method, and it is also called 'doi jong-yi' because it is made from mulberry or mulberry tree bark as a raw material. Such Hanji is currently used in various fields. In particular, when using Korean paper as wallpaper, it can prevent sick house syndrome, has excellent air permeability, has good humidity control function, has a deodorizing function and can keep indoor air comfortably, Can prevent skin allergy, and has a far infrared ray emissivity, which is beneficial for health, and is also used as a functional wallpaper finish material.

However, Korean paper wallpaper using such paper has a disadvantage that the dimensional stability is bad and the wall curvature is transferred, and the feeling of quality is lowered when it is applied. In addition, when a specific pattern or a picture is drawn or pasted on the surface of Korean paper, it is difficult to mass-produce it because it is required to attach a pattern or draw a picture, and the design itself has a limit to increase the aesthetic completeness.

The present invention provides a hanji board capable of preserving the properties of environment-friendly paper even when it is attached to the surface of the board.

The present invention provides a Korean paper board which can provide aesthetic designs such as specific patterns and drawings for a long period of time while maintaining the texture of Korean paper.

The present invention provides a Korean paper board capable of enhancing sound absorption.

The present invention provides a Hanji board which is easy to manufacture and can be mass-produced.

One aspect of the present invention is

Attaching the base paper from the upper surface of the board to a side or a lower surface portion; Attaching an engraved embossed engraved on a Korean paper onto the base paper; And

And coating the embossed paper with synthetic resin, natural oil or lacquer.

Since the Korean paperboard of the present invention is attached to the surface of the board using the base paper and the engraved paper, the aesthetic design such as a specific pattern or a picture can be provided for a long time while maintaining the texture of Korean paper. In addition, compared with the case of painting or embossing the surface of the Korean paper, the method of the present invention can easily produce the paper by using an engraved paper produced by cutting a predetermined pattern or figure on the paper using a designed frame, This is possible.

In addition, the paperboard of the present invention has a large void and is formed of a plurality of layers of thick paper having excellent sound-absorbing properties, and at the same time, the sound-absorbing property can be further improved because the depressed area is periodically repeated.

In addition, since the paper board of the present invention includes a nonwoven fabric or a back side paper that provides a constant tension on the back side of the board, all of the bonded paper sheets can be prevented from being separated, wrinkled, or torn.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention of the user, the operator, or the custom. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 shows a paperboard according to an embodiment of the present invention, FIG. 2 shows a method of manufacturing a paperboard according to an embodiment of the present invention, FIGS. 3 and 4 are photographs of the produced engraved paper, 5 is a photograph of the paper board manufactured in the present invention.

1 and 2, the paperboard of the present invention includes a board 10, a base 20, an engraved paper 30, an auxiliary paper 40, and a coating layer 50.

The built-in board 10 can be used not only as a building interior material such as MDF, gypsum board, LPM, HPM, plywood, plaster board, cement board, magnesium board,

The base paper 20 may be any known paper. Generally, it is possible to prepare a mixture by mixing the ground fiber and the pulp, and then grinding the mixture. For example, the pulp may be partially contained in 100% by weight of the pulp fiber or 100% by weight of the pulp fiber. For example, the pulp may be used in an amount of 20 to 60 parts by weight based on 100 parts by weight of the fiber.

The base paper has a weight of 10 to 70 g / m < 2 > and a thickness of 20 to 100 mu m can be used.

Referring to FIG. 2, the manufacturing method of the present invention includes the step of attaching the base paper to the upper surface of the board. Bonding of the base can be done by applying a known adhesive on the board first.

Further, in the present invention, the base paper may be extended from the upper surface of the board to a portion of the side surface or the lower surface. More specifically, the method of the present invention is not limited to attaching the base 20 only to the upper surface, but may be extended to the side surface or the lower surface.

The embossed paper 30 is a Korean paper embossed on a Korean paper with engraved engraving. The embossed paper 30 may have a thickness of 20 to 500 탆 or may be folded over two or more folds of the base paper. Since the engraved paper 30 has a predetermined thickness as described above, it is easy to form an engraved surface or to adhere to the base paper.

The engraved paper 30 can be formed by cutting out a predetermined pattern or a picture on a Korean paper.

In addition, the engraved paper 30 can be cut using a predetermined embossing blade, a laser beam, or the like.

The attachment of the engraved paper 30 may be performed by first applying an adhesive on the base paper, and then pressing the engraved paper 30 by pressing.

Referring to FIGS. 3 and 4, the engraved paper 30 is easy to cut off a specific pattern and implement a predetermined design with a relief angle.

Fig. 6 is an embossed pattern cut into Korean paper. In order to attach the embossed pattern on FIG. 6 on the base 20, the worker must attach the embossed pattern one by one, so that the work takes a long time and the design is not perfect due to the erroneous work.

On the other hand, since the operator can attach the engraved paper 30 to the base paper 20 at one time, it is easy to manufacture and the design is completed with high degree of mass production.

As described above, since the engraved paper 30 can be reproduced in large quantities, it is possible to attach a pattern having a high degree of completion to the board.

In addition, the paper having excellent sound-absorbing properties is formed thicker by the plurality of layers, and the sound-absorbing property can be further improved because the intaglio (recessed) region is periodically repeated.

The auxiliary paper 40 is attached to the bottom surface of the board and is bonded to the base paper. The auxiliary paper 40 provides a certain tension to the base paper, thereby preventing some deviation, wrinkling, tearing, etc. of the base paper. The auxiliary paper 40 may be a nonwoven fabric or paper having a tension similar to that of the base paper.

The coating layer 50 may be made of synthetic resin or natural resin. The coating layer 50 is coated on the engraved paper and the base paper. As the synthetic resin layer, a known polymer resin for a transparent film can be used. As the synthetic resin, acrylic resin, varnish, or the like may be used. As the natural resin, natural oil or lacquer can be used. The coating layer 50 may prevent foreign matter or moisture from penetrating into the engraved paper 30 and the base paper 20.

Further, the present invention may further include a flame retardant or a flame retardant layer on the synthetic resin layer (50). As the flame retardant and flame retardant, known water soluble phosphorus (ammonium) or inorganic flame retardants may be used. In addition, the present invention can form a flame retardant or a flame retardant layer on the board first.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
